This transceiver operates at a nominal wavelength of 1300 nm with an LC fiber connector interface with an external connector shield (HFBR-57E0).
Transmitter Section The transmitter section of the HFBR-57E0 utilizes a 1300 nm InGaAsP LED. This LED is packaged in the optical subassembly portion of the transmitter section. It is driven by a custom silicon IC which converts differential PECL logic signals, ECL referenced (shifted) to a +3.3 V supply, into an analog LED drive current.
Receiver Section The receiver section of the HFBR-57E0 utilizes an InGaAs PIN photodiode coupled to a custom silicon transimpedance preamplifier IC. It is packaged in the optical subassembly portion of the receiver. This PIN/preamplifier combination is coupled to a custom quantizer IC which provides the final pulse shaping for the logic output and the Loss of Signal (LOS) function. The data output is differential. The data output is PECL compatible, ECL referenced (shifted) to a +3.3 V power supply. This circuit also includes a loss of signal (LOS) detection circuit which provides an open collector logic high output in the absence of a usable input optical signal. The LOS output is +3.3 V TTL.
Applications x OC-3 SFP transceivers are designed for ATM LAN and WAN applications such as: ATM switches and routers SONET/SDH switch infrastructure x Multimode fiber ATM backbone links x Fast Ethernet
Loss of Signal The Loss of Signal (LOS) output indicates that the optical input signal to the receiver does not meet the minimum detectablelevel for FDDI and OC-3 compliant signals. When LOS is high it indicates loss of signal. When LOS is low it indicates normal operation. The LOS thresholds are set to indicate a definite optical fault has occurred (e.g., disconnected or broken fiber connection to receiver, failed transmitter).
Module Package The transceiver meets the Small Form Pluggable (SFP) industry standard package utilizing an integral LC duplex optical interface connector. The hot-pluggable capability of the SFP package allows the module to be installed at any time – even with the host system operating and on-line. This allows for system configuration changes or maintenance without system down time. The HFBR-57E0 uses a reliable 1300 nm LED source and requires a 3.3 V dc power supply for optimal design.
Module Diagrams Figure 1 illustrates the major functional components of the HFBR-57E0. The connection diagram of the module is shown in Figure 2. Figures 5 and 7 depict the external configuration and dimensions of the module.
Installation The HFBR-57E0 can be installed in or removed from any MultiSource Agreement (MSA) – compliant Small Form Pluggable port regardless of whether the host equip-

ment is operating or not. The module is simply inserted, electrical interface first, under finger pressure. Controlled hot-plugging is ensured by design and by 3-stage pin sequencing at the electrical interface. The module housing makes initial contact with the host board EMI shield mitigating potential damage due to Electro-Static Discharge (ESD). The 3-stage pin contact sequencing involves (1) Ground, (2) Power, and then (3) Signal pins, making contact with the host board surface mount connector in that order. This printed circuit board card-edge connector is depicted in Figure 2.

Serial Identification (EEPROM)
Electrostatic Discharge (ESD)
The HFBR-57E0 complies with the industry standard MSA that defines the serial identification protocol. This protocol uses the 2-wire serial CMOS E2PROM protocol of the ATMEL AT24C01A or equivalent. The contents of the HFBR-57E0 serial ID memory are defined in Table 3 as specified in the SFP MSA.
There are two conditions in which immunity to ESD damage is important. Table 1 documents our immunity to both of these conditions. The first condition is during handling of the transceiver prior to insertion into the transceiver port. To protect the transceiver, it is important to use normal ESD handling precautions.
Functional Data I/O
These precautions include using grounded wrist straps, workbenches, and floor mats in ESD controlled areas. The ESD sensitivity of the HFBR-57E0 is compatible with typical industry production environments. The second condition is static discharges to the exterior of the host equipment chassis after installation. To the extent that the duplex LC optical interface is exposed to the outside of the host equipment chassis, it may be subject to systemlevel ESD requirements. The ESD performance of the HFBR-57E0 exceeds typical industry standards.
The HFBR-57E0 fiberoptic transceiver is designed to accept industry standard differential signals. In order to reduce the number of passive components required on the customer’s board, Avago has included the functionality of the transmitter bias resistors and coupling capacitors within the fiberoptic module. The transceiver is compatible with an “ac-coupled” configuration and is internally terminated. Figure 5 depicts the functional diagram of the HFBR-57E0.
Immunity
Regulatory Compliance See Table 1 for transceiver Regulatory Compliance performance. The overall equipment design will determine the certification level. The transceiver performance is offered as a figure of merit to assist the designer.
Equipment hosting the HFBR-57E0 modules will be subjected to radio-frequency electro magnetic fields in some environments. These transceivers have good immunity to such fields due to their shielded design.

Notes: 1. Pin 2 connected to internal ground. 2. Mod-Def 0, 1, 2. are the module definition pins. They should be pulled up with a 4.7 K - 10 K: resistor on the host board to a supply less than VCCT +0.3 V or VCCR +0.3 V. Mod-Def 0 is grounded by the module to indicate that the module is present. Mod-Def 1 is clock line of two wire serial interface for optional serial ID. Mod-Def 2 is data line of two wire serial interface for optional serial ID. 3. LOS (Loss of Signal) is an open collector/drain output which should be pulled up externally with a 4.7 - 10 K:resistor on the host board to a supply < VCCT, R +0.3 V. When high, this output indicates the received optical power is below the worst case receiver sensitivity (as defined by the standard in use). Low indicates normal operation. In the low state, the output will be pulled to <0.8 V. 4. RD-/+: These are the differential receiver outputs. They are ac coupled 100 :differential lines which should be terminated with 100 : differential at the SERDES. The ac coupling is done inside the module and is thus not required on the host board. The voltage swing on these lines will be between 400 and 2000 mV differential (200 - 1000 mV single ended) when properly terminated. 5. VCCR and VCCT are the receiver and transmitter power supplies. They are defined as 2.97 - 3.63 V at the SFP connector pin. The maximum supply current is 230 mA and the associated in-rush current will typically be no more than 30 mA above steady state after 500 nanoseconds. 6. TD-/+: These are the differential transmitter inputs. They are ac coupled differential lines with 100 : differential termination inside the module. The ac coupling is done inside the module and is thus not required on the host board. The inputs will accept differential swings of 400 - 2000 mV (200 - 1000 mV single ended), though it is recommended that values between 400 and 1200 mV differential (200 - 600 mV single ended) be used for best EMI performance. These levels are compatible with CML and LVPECL voltage swings.

Notes: 1. This is the maximum voltage that can be applied across the Differential Transmitter Data Inputs to prevent damage to the input ESD protection circuit. 2. The data outputs are terminated with 50: . The Loss of Signal output is terminated with 50 : connected to a pull-up resistor of 4.7 K: tied to VCC. 3. The power supply current needed to operate the transmitter is provided to differential ECL circuitry. This circuitry maintains a nearly constant current flow from the power supply. Constant current operation helps to prevent unwanted electrical noise from being generated and conducted or emitted to neighboring circuitry. 4. This is the receiver supply current measured in mA. 5a. The power dissipation of the transmitter is calculated as the sum of the products of supply voltage and current. 5b. The power dissipation of the receiver is calculated as the sum of the products of supply voltage and currents, minus the sum of the products of the output voltages and currents. 6a. Differential Output Voltage is internally ac coupled. The Loss of Signal low and high voltages are measured with load condition as mentioned in note 2. 6b. Data and Data-bar outputs are squelched at LOS assert level. When the received light drops below LOS assert point, it will force receiver data and data-bar to go to steady PECL levels High and Low respectively. 7. The data output rise and fall times are measured between 20% and 80% levels.

Notes: 8. These optical power values are measured with the following conditions: The Beginning of Life (BOL) to the End of Life (EOL) optical power degradation is typically 1.5 dB per the industry convention for long wavelength LEDs. The actual degradation observed in Avago’s 1300 nm LED products is < 1 dB, as specified in this data sheet. Over the specified operating voltage and temperature ranges. With 25 MBd (12.5 MHz square-wave), input signal. At the end of one meter of noted optical fiber with cladding modes removed. The average power value can be converted to a peak power value by adding 3 dB. Higher output optical power transmitters are available on special request. Please consult with your local Avago sales representative for further details. 9. The relationship between Full Width Half Maximum and RMS values for Spectral Width is derived from the assumption of a Gaussian shaped spectrum which results in a 2.35 X RMS = FWHM relationship. 10. The optical rise and fall times are measured from 10% to 90% when the transmitter is driven by a 25 MBd (12.5 MHz square-wave) input signal. The ANSI T1E1.2 committee has designated the possibility of defining an eye pattern mask for the transmitter optical output as an item for further study. Avago will incorporate this requirement into the specifications for these products if it is defined. The HFBR-57E0 products typically comply with the template requirements of CCITT (now ITU-T) G.957 Section 3.2.5, Figure 2 for the STM- 1 rate, excluding the optical receiver filter normally associated with single mode fiber measurements which is the likely source for the ANSI T1E1.2 committee to follow in this matter.

13b. This specification is intended to indicate the performance of the receiver section of the transceiver when Input Optical Power signal characteristics are present per the following definitions. The Input Optical Power dynamic range from the minimum level (with a window time-width) to the maximum level is the range over which the receiver is guaranteed to provide output data with a Bit Error Rate (BER) better than or equal to 2.5 x 10-10. • At the Beginning of Life (BOL) • Over the specified operating temperature and voltage ranges • Input symbol pattern is the FDDI test pattern defined in FDDI PMD Annex A.5 with 4B/5B NRZI encoded data that contains a duty cycle base-line wander effect of 50 kHz. This sequence causes a near worst case condition for inter-symbol interference. • Receiver data window time-width is 2.13 ns or greater and centered at mid-symbol. This worst case window time-width is the minimum allowed eye-opening presented to the FDDI PHY PM_Data indication input (PHY input) per the example in FDDI PMD Annex E. This minimum window time-width of 2.13 ns is based upon the worst case FDDI PMD Active Input Interface optical conditions for peak-to-peak DCD (1.0 ns), DDJ (1.2 ns) and RJ (0.76 ns) presented to the receiver. To test a receiver with the worst case FDDI PMD Active Input jitter condition requires exacting control over DCD, DDJ and RJ jitter components that is difficult to implement with production test equipment. The receiver can be equivalently tested to the worst case FDDI PMD input jitter conditions and meet the minimum output data window time-width of 2.13 ns. This is accomplished by using a nearly ideal input optical signal (no DCD, insignificant DDJ and RJ) and measuring for a wider window time-width of 4.6 ns. This is possible due to the cumulative effect of jitter components through their superposition (DCD and DDJ are directly additive and RJ components are rms additive). Specifically, when a nearly ideal input optical test signal is used and the maximum receiver peak-to-peak jitter contributions of DCD (0.4 ns), DDJ (1.0 ns), and RJ (2.14 ns) exist, the minimum window time-width becomes 8.0 ns -0.4 ns - 1.0 ns - 2.14 ns = 4.46 ns, or conservatively 4.6 ns. This wider window time-width of 4.6 ns guarantees the FDDI PMD Annex E minimum window time-width of 2.13 ns under worst case input jitter conditions to the Avago receiver. • Transmitter operating with an IDLE Line State pattern, 125 MBd (62.5 MHz square-wave), input signal to simulate any cross-talk present between the transmitter and receiver sections of the transceiver. 14a. All conditions of Note 13a apply except that the measurement is made at the center of the symbol with no window time- width. 14b. All conditions of Note 13b apply except that the measurement is made at the center of the symbol with no window time-width. 15a. Systematic Jitter contributed by the receiver is defined as the combination of Duty Cycle Distortion and Data Dependent Jitter. Systematic Jitter is measured at 50% threshold using a 155.52 MBd (77.5 MHz square- wave), 223-1 psuedorandom data pattern input signal. 15b Duty Cycle Distortion contributed by the receiver is measured at the 50% threshold of the electrical output signal using an IDLE Line State, 125 MBd (62.5 MHz square-wave), input signal. The input optical power level is -20 dBm average. 15c. Data Dependent Jitter contributed by the receiver is specified with the FDDI DDJ test pattern described in the FDDI PMD Annex A.5. The input optical power level is -20 dBm average. 16a. Random Jitter contributed by the receiver is specified with a 155.52 MBd (77.5 MHz square- wave) input signal. 16b. Random Jitter contributed by the receiver is specified with an IDLE Line State, 125 MBd (62.5 MHz square-wave), input signal. The input optical power level is at maximum “PIN MIN (W)”. See Application Information - Transceiver Jitter Section for further information. 17. This value is measured during the transition from low to high levels of input optical power. 18. This value is measured during the transition from high to low levels of input optical power. At Loss of Signal assert, the receiver outputs Data Out and Data Out Bar go to steady PECL levels High and Low respectively. 19. The Loss of Signal output shall be de-asserted within 100 μs after a step increase of the Input Optical Power. 20. Loss of Signal output shall be asserted within 350 μs after a step decrease in the Input Optical Power. At Loss of Signal Assert, the receiver outputs Data Out and Data Out Bar go to steady PECL levels High and Low respectively. 21. The HFBR-57E0 transceiver complies with the requirements for the trade-offs between center wavelength, spectral width, and rise/fall times shown in Figure 3. This figure is derived from the FDDI PMD standard (ISO/IEC 9314-3 : 1990 and ANSI X3.166 - 1990) per the description in ANSI T1E1.2 Revision 3. The interpretation of this figure is that values of Center Wavelength and Spectral Width must lie along the appropriate Optical Rise/Fall Time curve.
